Title: Method and device for measuring concentration of gaseous methane
Inventor: SHINOHARA AKIO
IPC: G01N21/3504
Filed: 1982-09-25
Abstract: PURPOSE:To measure the concn. of the gaseous methane in a remote place with high accuracy without receiving the influence of any ce-existing material by using a quartz optical fiber as an optical transmission line, and making use of the specific absorption band of the gaseous methane having a specific wavelength. CONSTITUTION:The light of 1.3mum band and 1.6mum band emitted by a light emitting diode 1 are fed to a quartz optical fiber 3 and enters a measurement cell 4. The cell 4 is provided with optical couplers 4b, 4b' at both ends of a cylindrical body 4a. The body 4a is formed of a porous sintered body or a plastic foam having an open cell structure to permit the natural inflow and outflow of the measuring gas. The light emitted from the cell 4 is similarly fed to a quartz optical fiber 5, and is divided to two luminous fluxes by a beam splitter 7. The two luminous fluxes are divided to the light having the absorption wavelength of gaseous methane and the other wavelength by filters 8, 9. The ratio between the light intensities is signal processed by a photodetector 14 whereby the concn. of gaseous methane is measured.

IPC: F04C23/02
Filed: 1982-09-24
Abstract: PURPOSE:To prevent the pressure pulsation due to discharged coolant and pressure and pressure pulsation due to resonance in the internal chamber of a tank, etc. by installing a sound arrester concentrically with the tank internal chamber and opening the edge part of a discharge passage into said sound arrester and forming a discharge port at the position at equal distance from each outlet hole. CONSTITUTION:The lower fixing bearing 11 is constituted integrally with a box- shaped sound arrester 14, and the coolant discharged from a high-pressure chamber flows into the sound arrester 14 from an edge part 16 through a discharge passage 15 formed in a main shaft 9. Both outlet holes 20a and 20b in symmetrical position at right and left of the sound arrester 14 communicate to the inside of a sealed vessel 1. A discharge port 21 formed on a cover 19 communicates to the inside of the sound arrester 14. Each dimension of the outlet holes 20a and 20b is determined so that the resonance frequency determined by the capacity of the tank inside chamber 22 becomes equal to the fundamental frequency of pressure pulsation. The pressure pulsation in the fundamental frequency component which the coolant possesses is absorbed by the outlet holes 20a and 20b at the discharge port 21, and a resonator which is formed in the tank inside chamber 22.

Title: Pulse laser amplification system
Inventor: IWATA AKIHIKO
IPC: H01S3/097
Filed: 1987-07-06
Abstract: PURPOSE:To prevent an amplification efficiency due to an ageing change of a pulse generator for generating a high voltage pulse from decreasing and to enhance the stability, reliability and life of the system by providing a variable delay circuit between a trigger oscillator and a grid circuit. CONSTITUTION:A trigger output S3 from a trigger oscillator 1 is delayed by variable delay circuits 11a, 11b, and delay outputs S4, S5 are input to grid circuits 4a, 4b. Pulse generators 4a, 4b output high voltage pulses v2, v3 on the basis of output signals from the grid circuits. The pulse v2 operates an oscillator discharge tube 5a to generate a laser beam 6, which is amplified by an amplifier discharge tube 5b to output a laser beam 7. The displacement of the timing of the high voltage pulse due to the ageing changes of the grid circuits and the pulse generators can be corrected by altering the delay time of the delay output by the variable delay circuit to prevent the amplification efficiency from decreasing. The tubes 5a, 5b use metal vapor laser oscillators.

Title: Rear surface exposing device
Inventor: MURANO SHUNJI
IPC: B41J2/455
Filed: 1991-06-13
Abstract: PURPOSE:To reduce the diameter of a drum and to maintain the high accuracy of a focal position by joining the light emitting surface side of an LED array to a transparent flexible circuit board and setting a reference plane to be the reference for the accuracy of the focal length on the front surface side of chips. CONSTITUTION:An exposing head is constituted by joining and fixing the LED array 12 longitudinally to a rear surface side recessed part 111 of the transparent flexible circuit board 11 which is curved to the same diameter as the inside diameter of the drum by a fixing frame 13 and the front surface side of which comes into contact with the inside diameter. Signal wires are led to the outside of the drum via a connector provided on the rear surface side of the fixing frame 13 and are connected to a signal source. The disposing of such exposing means along the inner peripheral surface of the drum is possible and the reduction in the size of the photosensitive drum is facilitated by omitting a convergent lens. Since the surfaces of the LED chips 12a mounted on the circuit board exist on the light emitting surface side, the reference planes of the respective chips are unified regardless of the fluctuations in the height of the chips. The accuracy of the focal length is thus maintained with high accuracy.

Abstract: PROBLEM TO BE SOLVED: To transmit a response signal by reduced power by inserting a base station identification signal into a call signal string and transmitting a response signal directly spread-modulated through the use of a code obtained by the base station identification signal from a. receiver for radio call. SOLUTION: Base stations 41-1 to 41-n receive the call signal string transmitted from a central station 13 by using a line terminating device 21.

Terminals for radio call 16-1 and 16-2 send back the response signal directly spread-modulated by a code uniquely decided from the base station identification signal inserted to the received call signal string by the frequency Ff. Base stations 14-1 to 14-n receives the response signal by means of a receiver 25 with a code obtained from its own base station identification, and transmits it to the central station 13 through the device 21.
